8 Claims.

The present invention relates to mechanisms for translating a rotary motion into a reciprocatory motion, particularly for reciprocating a carriage. orra frame and. of a type adapted foreme bodiment in foodslicingmachines as a carriage stroke mechanism;

The. principal object ofithis inventionis .to provide a novel and. improved mechanism of the character described which is exceptionally compact in'construction and which has a newmode of operation.

Another. object is-to provide a mechanism of the typementioned wherein the arena of action of its moving parts requires but about half the space necessitated'by reciprocating. mechanisms of the class: employing an ordinary crank and connectingsrod assembly.

To attain these objects, and. others'which will become.- manifest as the disclosure proceeds, in an: embodiment of this invention, I" provide a driving shaft journalled in position normal to the pathof travel of. the'carriage, and an extensible mechanism driven therefrom, which first becomes extended and then collapsed or folded to oneside of the axis of the shaft and then to the other side thereof, which operation alternately repeated will cause the carriage to travel back andforth.

Thisinvention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired thatthe embodiment shown herein be deemed illustrative and-not restrictive, andthat the patent shall. cover Whatever features of. patentable novelty exist in. the invention. disclosed; reference being. had to the appended claimsrather-than. tothe specific description herein to indicate the scop of the invention.

In the accompanying drawings forming part of .this application, similar characters of reference indicate correspondingparts in all the views.

Fig. 1.is a plan view of: a slicing machine con-.

' struction, embodyingthe present-invention, show-'- ingthecarriage at one end of its stroke or travel.

Fig. 2.is a reduced section taken at line 22 in Fig. 1.

Figs. 3 and 4 are views similar to Fig. 1, showing a diagrammatic representation of the relative positions ofparts of the mechanism, at intermediate positionsof the carriage along its. line of travel.

Fig; 5. is; a similar view showing'the carriageat itsother remote position.

Fig. 61 isv afragmentary View showingza modified construction of the manner .ofsconnectingthe carriage .with. the reciprocating mechanism structure.

In the drawings, the numeral I 5, is used to designate generally the base frame of a slicing machine and the numeral It, a carriage slidably mounted thereon along the horizontal track memhers I! and I8. Within the frame, is journalled a horizontally positioned drive shaft l9, provided with: a; hand wheel 20, at its forward exteriorly extending rend, a bevel gear 22 at its other end interior the case or frame 15, and another bevel gear, 2! at the bearing 23. The usual circular knife. 24; pivotally mounted so that its plane is parallel to theline of travel of the carriage l6, is;revo1ved;by;a system of sprockets 25 and 26 carrying the chain 21, which receives motion by means of gear 28 in engagementwith the gear 22.

The bevel gear. 2|, is in engagement with gear 29, to drive a shaft 30, which is vertically positioned through. the base frame l5, and extends upward thereof, upon which external portion-is securely mounted. a gear 3| and a collar 32, between which isa loosely mounted link 33. Loosely mounted through the link 33, is a pin 34, which carries secured at its lower end a gear 35 in engagementwith the'aforesaid'gear 3|, and secured at its upper end is the link or crank 36 at an end of' the latter, which has integrally extending therefrom the cam follower element 31. The crank36, at its pin: 38, is linked to the end of another link designated as 39, which itself is pivotally secured at 40- to the carriage I6, and permitted to. beoscillated between the spaced stops 4land 42 secured to the carriage or integral with thelatter to extend in the'path of. travel of said member 39. As an. alternative construction, the crank 36, atits pin end-38-may be linked pivotally, to block- 43, which is free to oscillate along rod 44 between said stops 4| and 42.

Forfurther reference herein to facilitate explanation, 30, 34, 38-and 40, may be deemed points, in the plan views in the drawings. When the carriage I6; is at either endof its stroke, these points are colinear. Ona line perpendicularthereto, at opposite sides of point 30, and equally, spaced therefrom, there are secured to the frame IS, the cam members 45 and 46 respectively, for the guidance of thecam follower 31, when the-latter reaches their respective vicinities.

In operation, upon rotating the hand wheel 20, it is evident that the knife 24 will revolve, as also willshaft 30, and the pin 34; the latter about its own axis travelling in a circle having. point 30 as the centre. of its path. The links 33 and 36 willbe moved to fold whereby they set one over the; other, and point 38 will approach point 30; whereby the carriage IE will be slid along the track members I l and l8to'theilineof the cam members 45. and. 46, andthefcam-follower 31, will contactJthe cam member 45.- The lines defined by points 34, 33, and by. points. 3.4 .39; willnext coincide. It is necessary at this time that said coinciding lines assume an angular relation increasing in the direction of carriage travel. Since point 34 will continue to move about 30, the action of the cam 45 will accomplish the required Figs. 3 and 4, to the remote end of its travel at the other side of point 30, as shown in Fig. 5.

' Upon continued rotation of the hand wheel 20,

the carriage IE, will be slid back to its initial position, and the unfolding of the links 33 and 36, will occur this time at the cam member 46. The cycle is then repeated as many times as required.

The mechanism herein set forthgis especially compact and permits the building of slicing machines which require but small space, and is adaptable for embodiment in many types of ma chines and devices which include particularly reciprocating carriages, or components requiring similar motions as are accomplished by the present invention. Simultaneously herewith, I have filed a companion application for patent to cover a Cross feed mechanism for slicing machines, wherein I describe means related to the subject matter herein to accomplish an intermittent sliding movement of a platform on the carriage, whereby the substance to be sliced is advanced periodically to a position forward of the plane of the knife, prior to the commencement of each cycle of movement of the carriage [6 herein.

Having fully disclosed a preferred embodiment of my present invention as herein described, I
